Examples
# NOT RUN {
## random points
plot(tri.mesh(rpois(100,lambda=20),rpois(100,lambda=20),duplicate="remove"))
## use a part of the quakes data set:
data(quakes)
quakes.part<-quakes[(quakes[,1]<=-10.78 & quakes[,1]>=-19.4 &
                     quakes[,2]<=182.29 & quakes[,2]>=165.77),]
quakes.tri<-tri.mesh(quakes.part$lon, quakes.part$lat, duplicate="remove")
plot(quakes.tri)
## use the whole quakes data set
## (will not work with standard memory settings, hence commented out)
## plot(tri.mesh(quakes$lon, quakes$lat, duplicate="remove"), do.points=F)
# }
